Abstract

Frullanti, Elisa La Vecchia, Carlo Boffetta, Paolo Zocchetti, Carlo eng Meta-Analysis Research Support, Non-U.S. Gov't Review Netherlands 2012/03/24 06:00 Dig Liver Dis. 2012 Sep;44(9):775-9. doi: 10.1016/j.dld.2012.02.007. Epub 2012 Mar 21. ; International audience ; BACKGROUND: It has been proposed that vinyl chloride exposure is associated with increased risk of death from cirrhosis, although epidemiologic evidence is limited. METHODS: We analyzed the risk of death from cirrhosis by occupational vinyl chloride exposure by conducting a meta-analysis on seven available studies, including more than 40,000 workers exposed to vinyl chloride mostly in North America and Europe, with a total of 203 deaths from cirrhosis. RESULTS: All epidemiological studies on vinyl chloride exposure and risk of death from cirrhosis resulted in an overall relative risk of 0.73 (95% confidence interval 0.61-0.87). Thus, the epidemiologic evidence does not suggest an excess mortality from cirrhosis in vinyl chloride-exposed workers; this is consistent with histopathological observations in livers of angiosarcoma patients and of vinyl chloride-exposed rodents revealing no signs of cirrhosis. CONCLUSION: Overall, our findings indicate the absence of increased risk of death from cirrhosis in vinyl chloride-exposed workers.
